1. I maxed out the level of the cleric villager to master so that I can trade an ender pearl. I used gold in trading them. I successfully trade one ender pearl. After some time, when I checked the cleric back so I can trade again, it went back to apprentice level.
2. I then maxed it our again to master level since I wanted to trade another ender pearl, when I got back after logging off the game, it went back to apprentice again.
3. I am searching for a librarian with Riptide 3 trade. When I finally saw one, I traded it with paper. When I logged off and logged in again to play the game, the trades of the villager are different. They got refreshed with another trades despite locking it with apprentice level.
4. AND THIS ONE, I zombified the villagers I have and cured them using golden apples. Since I put them in a small room, I transported them to the area where I zombified and cured them. Then I put them back to the small room I made for them. It was all okay. After curing all the villagers I have in my trading hall, I logged off the game. When I went back, the villagers got doubled! When I checked, the small room has two villagers----one with the cured ones and one with the uncured ones. It feels like they are the spirit of the previous villager.

Please help this out. It's bugging me now. Hope this will be resolved soon. Thanks
